Drought and Desertification: How Robots Might Help

Hallie Siegel writes Groundwater levels in California's Central Valley are down to historic lows and reservoirs have been depleted following four consecutive years of severe drought in the state. California is set to introduce water rationing in the coming weeks, and though the new rationing rules will focus on urban areas and not farms for the time being, they serve as a warning bell to farmers who will inevitably need to adapt to the effects of climate change on food production. John Payne argues that long term solutions are needed to help make agriculture drought resistant and looks at some of the ways that robotics might help.

      Remember those people grow your food.

      But robots could *really* help. Think instead of huge sprinkler systems that spray millions of gallons you had a few solar powered robots running around spraying just the right amount of water on each plant right when the needed it, not too much and not too little. Each plant could also be photographed and watched for pests or disease. Meaning less pesticides and less fertilizers needed. Marked in the computer overnight to be hit up for a touch up of the correct pesticide the next day by a different robot.

      This is not something that would increase yields a little bit. It would invert the whole industry and crash prices.

      You think these people are going to give up their land because 'you dont like them'? They dont care.

      Scarcity will make this happen. There is too much money on the line. Besides someone *else* already owns those 'old permafrost' lands. You may have not noticed but they basically turned a desert into farm land already. You did not notice because it has always been that way for you. But it was not always that way.

The solution to California's water problems is simple: have California farmers pay market rates for water and stop subsidizing farmers.

      Sure, and watch the price of just about everything you eat triple over the next few months. Here's a little info of where the cost of that water will get passed along to the consumer. California grows so much because its "natural state" is quite good for growing a lot of the things we eat. It's the unnatural things we humans are doing that is spoiling that.

      Yeah, California produces the most expensive crops that total 11.63% of the total dollar value. Food staples primarily come from elsewhere. Worse case scenario most nuts, tropical fruits, and some vegetables will be more expensive while everything else will remain largely unchanged.

      Remember that California has the most organized, aggressive, and well-funded (pun intended), body of agribusiness in the US.

      I don't know, but shipping them water may be more cost effective than judging them.

      That's quite possible. If they were paying market prices for water, we could compare the market price of water to the cost of shipping water. Then we'd know.

      So long as California insists on charging below market rates for water, we can't know things like this. We simply don't know how much water is worth in California. Maybe they'd grow less produce and other states would build more greenhouses. Maybe they'd ship in water from the North. Maybe they'd build more desalination. Markets are good at balancing competing needs like this in a decentralized way. Governments are pretty bad at it. To do this with a government, we'd need to create a centralized water authority--preferably at the global level (since produce markets are global). A market can have global impact even if only California changes.

      My personal suggestion would be for California to build salt water greenhouses. They have plentiful access to salt water. Salt water greenhouses produce excess fresh water and minimize water loss due to evaporation (a lot of irrigation water evaporates and is lost to the atmosphere). Unlike other desalination projects, they are naturally solar powered. This would allow them to continue growing produce for the rest of the country and increase the available fresh water. By allowing people to bypass rationing, it would also make the ground and air wetter.

      One of the problems with rationing is that it exacerbates the problem. Watering the lawn doesn't just grow grass. It also soaks down further, replenishing the aquifer. And it evaporates, making the air moister, which leads to precipitation. Increasing the supply allows this, pushing back against desertification. Rationing does the reverse, speeding desertification outside the approved rationing destinations.

      Why would it "go away"? It would simply be produced elsewhere, at whatever it actually costs, probably even cheaper (the same special interests that get cheap water also manage to keep prices high and imports restricted). Ideally, it might be imported from Central and South America, improving economic conditions there, lessening the refugee problem, and helping economic development, while providing us with cheaper food.

      California is handling their water issue poorly; but they are, in effect, subsidising the rest of the country’s food prices.

      And why is that a good thing? Food would be abundant and cheap in the US even without California; food makes up a tiny fraction of what Americans spend their money on. And agriculture and mining together only account for 2% of California's GDP.

      But the water and money that flows into subsidizing agriculture in California comes from somewhere. And you may notice that California is also the tech hub of the nation, and it is paying dearly: agricultural subsidies and regulations contribute to land scarcity and make living in California harder and more costly. So, the dollar or two the rest of America may or may not save on groceries a month is likely paid for in substantially higher tech prices, and even worse, substantially slower tech innovation, and the long term costs of that are enormous.
